I have worked with Mr. Kersh for approximately five years. I have come to rely on Eli for detailed information on aquatic weed issues. I have been impressed with his overall understanding of plant biology and a very deep understanding of the very complex area of aquatic biology and environment.

I can say, unequivocally, that Eli's made me a better salesperson, a better applicator, and a better person for having known him. As a team member, Eli's strength lies in presenting alternative pathways to solve complex environmental problems, and to provide meaningful challenges whenever necessary in established process.

Eli at LakeTech has provided PCA services for me over the past 2 years, assisting me with the diagnosis and treatment plan for a large property in Santa Cruz County dealing with invasive vegetation.
I highly recommend LakeTech for vegetation management and invasive weed consulting.

Eli has been very helpful in providing me with guidance when working on various lake management projects through GIS applications. His expertise in the field and enthusiasm to help makes it easy a pleasure to work with Eli.

Eli has been excellent to work with. He's very personable and always available to answer limnology questions/have discussions. I value his knowledge of lake management, willingness and passion to explain/teach, honesty, and integrity for good science. Can't recommend Eli or his services enough.

As the noxious weeds coordinator for the Nevada Department of Agriculture, I had the privilege of working with Eli while cosponsoring training events for licensed and certified applicators throughout the state as well as assisting landowners address noxious weed infestations in environmentally sensitive areas. While assisting me with these duties, I found his superior communication skills coupled with his technical knowledge effectively relayed complex information to a wide range of interested parties from skilled to novice. Thanks for the help Eli.

Eli is the epitome of professionalism. In addition to providing quality products, Eli goes far beyond and has helped me understand and use them as efficiently as possible. Eli has been an immense source of knowledge and I HIGHLY recommend him for any opportunity or endeavor. As a person Eli is up front and honest and I genuinely enjoy working and learning from him. His understanding comes from actually having put in the work himself rather than reading literature and has made him one of my most valued tools. I look forward to working and purchasing from Eli for years to come!

I've worked with Eli for a number of years. He is very dedicated to the customer in detailing the problem and the solution. He has a good number of aquatic industry resources he draws on when needed. Best of all, he listens and follows advice when coming from those he has asked for assistance from. He has volunteered his time in numerous weed societies.
